New for 2021 is Hubcap, in his Generation 2 incarnation. Hubcap reuses the Cliffjumper mold, but the tooling is modified to provide a new headdesign, and the Porsche 924 model does not have a spoiler. For his Generation 2 release in 1993, Hubcap had a vacuum-metallized finish that rendered him in a gleaming red color.
The combined form of the Universe Micromaster Aerialbots is Superion, an amalgamation of six robots plus their pack-in accessories that serve as connectors, head, and extremities of the gestalt warrior. While in Japan, the original source of the design ( Sixwing , 1992) was available in a collected set, this combiner needed to be purchased one bot at a time in the 2007 Universe release.
